MOORE AND KENNETH L. MOORE, 0FMUNCIE, INDIANA MOLDER S FLASK 1 vision of a simple and efi'ective meansfor con necting the flask walls, so that the flask may be readilyassembled for use and thereafter knocked down or separated through theuse of a small hammer or like tool or implement.

15 Another object of the invention is the provision of a novel form ofpartition bar which may be quickly secured within or removed from theflask, or may be adjusted to any desired position therein.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings Figure 1 is a plan view partly in section showing aflask constructed in accordance with the invention.

30 Figure 2 is an elevation looking at one side 35 tively on the lines Hand 5-5 of Figure 1.

Figure 6 is a fragmentary view showing one end of one of the walls ofthe flask.

Figure 7 is an edge view of the same.

Figure 8 is a view similar to Figure 6 but showing the end of anotherwall of the flask.

Figure 9 is an edge view of the flask wall shown in Figure 8.

Figure 1-0 is a detail perspective view of the assembling wedge.

Referring to the drawings in detail wherein like characters of referencedenote corre sponding parts, the flask as shown includes a cope 10 and anowel or drag 11 which are arranged in superimposed relation as shown inthe drawings. The cope 10 and drag 11 are of like construction andcomprise pairs of walls 12 of like construction and pairs of walls 13also of like construction. The walls 12 and 13 may be made of varioussizes and are interchangeable so that when the walls are connected in amanner to .be described, flasks of different sizes and shapes maybemade. The walls 13 are provided near each; end with transverselydisposed elongated-open ings 14, the walls at each end of these openingsbeing reinforced as shown at 15. Ex tending from the walls 13 arehandles 16 by means of which the mold may be conveniently moved. Thesehandles 16 may be replaced by centrally located trunnions for largeflasks, so that the latter may be conveniently handled by a crane. Inaddition, thewalls 13 are provided with laterally extending aperturedlugs 17 which receive locking pins 18, so that the cope and drag may beproperly assembled. H p

Thewalls 12 have extending therefrom ears 19 which are provided withopenings. 20, These ears are adapted to extend through the opening 14 toreceive removable wedges 21. The walls 12 are provided with laterally extending lugs 22 which form shoulders adjacent the inner edges of. theopenings 20 and these shoulders are adapted to abut one face of thewalls 13, so that when the wedges 89 21 are arranged within the openings20, these wedges will engage the outer faces of the walls13 and clampthese walls between the lugs and wedges. The outer walls of the openings20 are inclined as shown at 23 to conform to the inclined faces of thewedges21.

It will be apparent from the foregoing description and accompanyingdrawings that the mold units may be quickly assembled, while a lightblow from a hammer or other implement will remove the wedgesand permitof the separation of the mol V The cope is provided along opposite wallswith longitudinally extending ribs 24. These ribs are adapted to beengaged by a partition bar 25 which is provided along one edge withspaced recesses 26 for this purpose. The other edge of the bar 25 isinclined as shown at 27 and pivotally secured to this end of the bar 25as shown at28 is a member 29; This member is provided with spacedrecesses 30' similar to the recesses 26 so as to engage one of the ribs24 and in order to hold the member 29 and the opposite end of the bar 25in such engagement, a wedge 30 is inserted between the member 29 and theadjacent beveled edge 27 of the bar.

The bar 25 may be adjustably raised or lowered, or it may be adjustedlaterally to hold the sand within the cope.

From the foregoing description and accompanying drawings it will be seenthat the invention provides a flask which is made up of inexpensiveinterchangeable units which are readily assembled or knocked down, sothat from a stock of such units a number of flasks of different sizesmay be assembled. When the flask is not in use the units may bedisassembled and stored in a convenient place.

The invention is susceptible of various. changes in its form,proportions and 11311101 details of construction and the right hereinreserved to make such changes as properly fall within the scope'of theappended claim.

Having described the invention what is claimed is o In a molders flask,separate pairs of side members and separate pairs of end members, eachof said members defining an interchangeable unit,'one pair of saidmembers having openings adjacent each end, ears extending from oppositeends of each of the other pair of members for passage through theopenings of the first referred to pair, said ears also having openingstherethrough, shoulders extending laterally from the ear carryingmembers adjacent to and parallel with said open ings to engage the othermembers between the openings and outer ends of said other members toengage the other members, and Wedges removably positioned within theopen ings of the ears and also engaging said other members to clamp thelatter between the shoulders and wedges and removably hold the partsassembled.

' In testlmony whereof we aflix our signatures.
